Grade: Homopolymer - PTFE Filled - 20%
Composition: POM H 20% PTFE
Form: Granule
Material: Polyoxymethylene (POM)
Commodity: Polymers
Nominal Granule Size:
3mm
Color:
Natural
20% PTFE Fiber Filled POM Granules combine the high stiffness, fatigue resistance, and dimensional stability of polyoxymethylene (POM) with the exceptional self-lubricating and low-friction characteristics of polytetrafluoroethylene (PTFE) fibers. The 20% PTFE fiber reinforcement significantly reduces wear and friction while enhancing impact performance, making it ideal for moving parts operating under high load and repeated cycling. This material is extensively applied in automotive systems, industrial machinery, and precision instrumentation, where long-term wear resistance and smooth operation are essential. Specific uses include low-maintenance gears and bearings, sealing elements in pumps and valves, and sliding components in automation equipment. Its value in research stems from its tunable tribological performance, enabling the study and design of advanced self-lubricating composites. By delivering a synergy of strength, wear resistance, and processability, it remains a crucial polymer engineering material for scientific advancement and industrial innovation.
